T0 at whom it may concern.-

Be it known that I, WALTER S. OOE, of New York, (Brooklyn,) county ofKings, and State of New York, have invented a new and useful Improvementin Linotype-Machines, of which the following is a specification.

My invention relates to an improvement in the Mergenthaler linotypemachine represented in Letters Patent of the United States No. 557,000,dated March 24, 1896, and also in improved form in Patent N 0.5463054,dated September 10, 1895, and now in general use in the printing-officesof the United States, the object being to prevent the accidentaldelivery of molten metal among the working parts of the machine, ashereinafter more fully explained.

In the commercial machine of the present daya pot containing a supply ofmolten metal is provided with a pump, by which the metal is delivered atintervals into the slotted mold and against the line of matricescomposed temporarily against the face of the mold, the result being theproduction of a slug or linotype bearing on its edge, in relief,characters to produce one line of print. The mold is carried in avertical wheel, which is in turn mounted on the arm of a horizontalmovable support or slide,commonly known as a moldslide, which is in turnoperated by a lever actuated by a cam. It is at times necessary to gainaccess to the rear face of the mold, and for this purpose themold-operating lever is mounted as in Patent No. 546,054, so that it maybe instantly disconnected from the slide in order to admit of themold-wheel being drawn forward away from the meltingpot, so as to afforda Wide space between the pot and the mold. During this separation of theparts it is important that the action of the pump for delivering metalthrough the mouth of the pot shall be prevented, and it is to this endthat the present improvement is directed; and it consists in apump-locking mechanism connected with a device for throwing themold-slide-operating lever into and out of action, so that when themold-slide is disconnected and in position to be moved forward the pumpis locked out of action.

I have shown my improvement as incorporated in the ordinary linotype ofthe present day; but it is to be understood that it may be modified inform and used in other analogous machines, provided no departure is madefrom the general mode of action herein described.

The drawings are limited to those operations of the machine which arenecessary to an understanding of the invention. In all other respectsthe machine may be of ordinary construction.

Referring to the drawings, Figure 1 is a side elevation of themelting-pot, mold-wheel, pump-lever, and cooperating parts with my stopor locking device added thereto, the mold-slide being released. Fig. 2is a similar View with the parts in operative position. Fig. 3 is a topplan view of the parts shown in the foregoing figure, the top of themainframe standard being broken away to expose other parts to view.Figs. land 5 are elevations, looking from the rear of the machine towardthe front, as indicated by the arrows in Figs. 1 and 2, showing,respectively, the positions of the parts when the mold-slide is unlockedand when it is locked.

Referring to the drawings, A represents a vertical mold-wheel carryingthe mold a, having a slot therethrough from front to back, as shown.

Bis the horizontal movable mold-slide, situated in guides O in the mainframe and having at its forward end a lateral arm, by which the journalof the mold-wheel is supported, as

shown.

D is a vertical cam-wheel acting on the roller F at the lower end of thelever E, which also carries a second roller G, adapted to enter avertical notch H in the rear end of the mold-slide, so that the motionof the lever E, caused by the cam-wheel, will effect a backward andforward movement of the mold slide and wheel.

The leverE is suspended at its upper end by a pivot-pin I between theforward arms of the hand-lever J, supported at the middle point on thehorizontal stud K, fixed to the main frame. When the rear end of thelever is depressed, its forward end rises, lifting the lever E andraising the roller G out of the notch H in the mold-slide B, thusreleasing the slide, so that it'may be moved forward. When the lever Jis again elevated, it lowers the parts to their operative positions, asshown in Fig. 2.

M is a horizontal spring-actuating pin mounted in the main frame inorder to pass over or under the hand-lever, so as to hold the lever E inits operative or inoperative position, as demanded.

N represents the melting-pot, mounted behind the mold-Wheel, as usual,and provided on the rear side with a spring-supporting lever 0, throughwhich it receives motion from the cam-wheel, unnecessary to describe.

P is the pump-lever, mounted at Q on a fixed horizontal pivot, connectedat its forward end to the pump-plunger R and depressed by aspring-actuated rod S, bearing midway of its length.

All of the foregoing parts are constructed and arranged to operate inthe usual manner, except that I now provide the rear end of thepump-lever P with an upwardly-extending arm T and provide the hand-leverJ with a rearwardly-extending arm or shoulder U. These last-named partsare so proportioned and arranged that when the hand-lever J is depressedto lift the lever E and release the mold-slide the shoulder U is carrieddown in front of the arm T on the pump-lever, as shown in Fig. 1, and inthis manner the pumplever is locked in its elevated and normal position,so that it is impossible for the pump to operate While the mold is movedforward. In this manner the accidental delivery of molten metal from thepot is positively prevented Whenever the mold-slide is unlocked.

What I claim as my invention is- 1. As an improvement inlinotype-machines, the combination of a pump-locking device and amold-slide-operating mechanism acting to prevent the action of the pumpwhen the mold-slide is released.

2. In a linotype-machine, the combination of a pump-lever andalever-eontrolling moldslide-operating device, the last-named leverarranged to lock the first, substantially as described.

In testimony whereof I hereunto set my hand, this 30th day of November,1898, in the presence of two attesting Witnesses.
